IMPROVEME-NT IN PLOWS.

Specification forming part of Letters Patent No. 29,726, dated August 21, 1860.

following is a full and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, so as to enable others skilled in the art to make use of myinvention.-

Figure 1 represents the frame b a, moldboard a, point (I, and side e, when fastened together so as to form aoomplete plow, with the exception of the wood-work or stock of the plow; Fig. a view of the inner side of the side hoard, e,- Fig. 3, a view of the bottom side of the mold-board a; Fig. 4, a bottom view ot' the point (I, and Fig. 5 an inside view of the frame I) c.

The frame of my plow consists of an upright standard, I), provided with a curved flange or wing, c a, (see Fig. 5,) and with a rece s, 1 It i m, in the lower part of its side.

The mold-board a is made \\ith a zigzag edge, 9 'ij k, Fig. 3, and its bottom is provided with two projections or hooks, ff. The curvature of the wing or flange c c of the frame is such as to tit the curvature of the mold-board. The point d is made with an edge, 9 Hit, Fig. 4, on its upper side, and with an edge, is l m, Fig. 4, on its side. The side board, 6, Fig. 2, is made with an edge, 1' k l m. There is no projection on the frame b 0, against whiclrthc mold-board and point rest. The mold-board is flush with the side of the standard I) on the line k s t, as seen in Fig. 1, and thus, as there is no projection on the standard against which the edge ks t-of the mold-boardrests, the-moldboard might be extended beyond the line [cs 16, so as to answer the purposes of various kinds of plows. The shape of the mold-board is only limited on the line 9 i j it; but in every other direction it may be shaped at pleasure, making one plow answer the several purposes of subsoil, cultivating, sod, and stubble and fatlow plow of any size and shape.

The mold-board is fastened to the wing c a of the frame-by passing the hooksff, projecting from the bottom surface of the mold-board, through the slots [L h in the wing, so that the overlapping ends of the hooks will come to rest against the bottom surface of the wing, and a bolt is then inserted through the holesnin the mold-board and wing. The side board, (2, is at tached to the frame by placing the part of its edge k 7' against the edge It 1" of the recess 1' It 5m in the side ot'thc standard and passing a bolt through the holes 1) in the side board and standard. The point 61 is then brought up so that its edge 9 i kjoins the edge g ij 7; of the mold-board, and its edge lclm rests against the edge It l Ill of the side board, all as shown in Fig.1. A bolt passing through the holeso in the Wing c and point (I fastens the latter to the wing.

The four parts of the plow, being thus fastened together and joining on the line 9 'ij k m l r, serve to brace each other and form a plow which, for all practical purposes, is as substantial as it made of one piece, while the moldboard, point, and side board may be varied in shape in any direction, excepton the line g i It 112 Zr, where they are joined, for the purpose of adapting the plow to the various purposes ot' a subsoil, cultivating, sod plow, &c.

It will also be seen that all the wearing parts of the frame of my plow are covered by the mold-board, point, and side board, so that the frame will not be worn at all, and that one frame may answer any length of time.

Havingdesoribed my invention, whatIclaim therein as new, and desire to secure by Letters Patent, is

The construction and relative arrangement of the wing 0 c and mold-board a g ij it, fastened together by means of bolt n and hooks ff and slots h h, the plow-standard I) t s 1', the point d g ij k l m, and-the landside er lm, all as shown and described.
